Using the Orbiter 450 lantern is super easy. To turn it on, just press the buttons on the two - button interface. You can adjust the brightness and switch between different light modes like full - spectrum color, campfire light, and rainbow cycle modes. When it's time to charge, use the USB - C port to charge the lantern's 2000 mAh lithium - ion battery. You can also use the USB - A port to charge your small electronics like your phone. As for maintenance, keep it clean and dry. Since it has an IPX4 stormproof rating, it can handle a bit of water, but don't submerge it. When you're transporting it, make sure the patented electronic lock is on to prevent it from turning on by mistake.
